Step 1: Prep the Ingredients
Cut the beef chuck roast into 1.5-inch cubes.
Chop the carrots, potatoes, onions, and celery into bite-sized pieces.
Mince the garlic and measure out the seasonings.
Step 2: Brown the Beef (Optional, but Recommended)
Heat 1 tbsp olive oil in a large skillet over medium-high heat.
Sear the beef in batches for 2-3 minutes per side, until browned.
Transfer the browned beef to the crockpot.
Step 3: Add Everything to the Slow Cooker
Layer the potatoes and carrots at the bottom, followed by the seared beef.
Add onions, celery, garlic, Worcestershire sauce, tomato paste, and seasonings.
Pour in the beef broth, ensuring the ingredients are covered.
Add bay leaves on top.
Step 4: Slow Cook to Perfection
Low Setting: Cook for 8-10 hours (best for tender beef).
High Setting: Cook for 4-6 hours (faster but slightly less tender).
Step 5: Thicken the Stew (Optional)
If the stew is too thin, mix 2 tbsp cornstarch with 2 tbsp cold water in a small bowl.
Stir it into the stew 30 minutes before serving and cook uncovered on high until thickened.
Step 6: Taste & Serve
Remove the bay leaves.
Taste and adjust salt and pepper as needed.
Serve warm with crusty bread or over mashed potatoes.
